"There are obvious logistical benefits to limiting it to male members of the team, but also male pee is preferable to women's, as the male stuff is apparently less acidic."
By the end of the year, it was calculated that the 10 men from the 70-strong garden and estates team will make more 1,000 individual trips to the pee bale, contributing towards the compost for the estate.
The estate said it will have saved up to 30% of its daily water use by not having to flush the loo so many times.
Rosemary Hooper, Wimpole estate's in-house master composter, said: "Most people can compost in some way in their own gardens.
"Peeing on a compost heap activates the composting process, helps to produce a ready supply of lovely organic matter to add back to the garden.
"Adding a little pee just helps get it all going; it's totally safe and a bit of fun too."
